A petition for modification has been submitted to the Mine Safety and Health Administration (MSHA) by Rockwell Mining, LLC, seeking to change the existing safety standards. They request permission to use non-approved Powered Air Purifying Respirators (PAPRs), specifically the CleanSpace EX and 3M Versaflo TR-800 models, near certain mining areas. The petition outlines the safety and training measures that would accompany the use of these devices to ensure they maintain or improve safety standards for miners. The petition emphasizes alternatives for miners with facial hair and those who find regular respirators uncomfortable, ensuring safety is not compromised.
Simple Explanation
Rockwell Mining wants to use special breathing masks called PAPRs in mining areas, which might help people with beards or those not comfortable with regular masks, and they're making sure safety stays just as good or better.
